iio: magnetometer: Only declare ACPI table when ACPI is enable
Don't inflate the kernel size with data that isn't used. The conditional declaration also fixes the following warning when building with clang: drivers/iio/magnetometer/ak8975.c:704:36: error: variable 'ak_acpi_match' is not needed and will not be emitted [-Werror,-Wunneeded-internal-declaration] Signed-off-by: Matthias Kaehlcke <mka@chromium.org> Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
